Not entirely sure how authentic this is. I followed the shoyu ramen recipe from Joshua Wisseman.
If you’re worried about authenticity, probably compare notes with native cooks, but more importantly, check to see if the ingredients are correct. Very easy to get bastardised ingredients; as an example, living in an Asian country, I used to have a hell of a time getting the right herbs and vegetables for doing certain Western dishes with, and very common to get some pre-packaged “mix” of herbs instead.
Do Asian countries have Western markets the same way Western countries have Asian markets?
Japanese food is the dogs bollocks and I have no idea why.
I’m not even hugely keen on fish. But fuck those guys on that crazy little island make some good tucker.
